High Power Factor LED Replacement T8 Fluorescent Tube

Introduction This application note describes the principles and design equations required for the design of a high brightness LED lamp using the AL9910. The equations are then used to demonstrate the design of a universal, offline, high power factor (PF), 13W LED lamp suitable for use as the re
